[Mono-dev] Status of Mono Garbage Collector?
Tree month ago (11/17/2006) Miguel said : Paolo has been working on a new garbage collector (GC) engine. Currently Mono GC interface is almost pluggable (the work to plug different GCs was done a few months ago). The new GC engine is a precise, generational, compacting collector. This means that the Mono GC will be able to return memory to the operating system when it no longer needs it. We are making a few tradeoffs to ship this version of the collector quickly. For instance this new GC will treat the stack conservatively has two effects: it makes it easy for embedders of Mono to use the new GC but it also might flag a lot of pinned objects. We hope that the new GC can be tested in February or March, the code will start landing in December. I'd want to know more about the statut of this new GC. I think, that mono will be usable (on a desktop) (try to use beagle...) only if there's a good precise GC... There's too many memory leak problems with the current boehm GC... (even on a server, i must restart apache once a week to avoid memory problem).

[Mono-dev] Undeclared identifier in threads.c/VS2005
Hi all,I'm currently trying to build Mono in Visual Studio 2005, but it seems that there is undeclared identifier __func__ in threads.c which causes build to fail. Revision of threads.c is 57160. Looks like latest changes to that file have been made six days ago, am I the only one having these problems?

[Mono-dev] gtk-dotnet performance
Hello,
I tried posting a similar question to the Gtk list but haven't received any
response there, so I forgive me for trying my luck here as well.
I'm am trying to use gtk-dotnet functionality to copy a
System.Drawing.Bitmap to a Gtk.DrawingArea.
My first approach was to follow exactly the sample code provided on the mono
site (http://www.mono-project.com/GtkSharpNewInVersion2x):
protected override bool OnExposeEvent (Gdk.EventExpose args)
{
using (Graphics g = Gtk.DotNet.Graphics.FromDrawable (args.Window)){
g.DrawImage(...);
}
return true;
}
However, I'm finding that the performance of this is unpredictable- if
several expose events are generated in quick succession (eg to create an
animation), the first will execute quickly ( 100 msec) but the next 3 or 4
expose events will take much longer (~500 msec).
I thought there might be some overhead with re-creating the Graphics object
each time, so my second approach was to try using a static intermediate
Pixmap as follows:
// create a static pixmap
Pixmap pixmap = new Pixmap(...);
// create a static graphics object
Graphics g = Gtk.DotNet.Graphics.FromDrawable (pixmap);
protected override bool OnExposeEvent (Gdk.EventExpose args)
{
// Draw on the static pixmap, through the previously
// created Graphics
g.DrawImage(...);
args.Window.DrawDrawable(..., pixmap, ...);
return true;
}
However, in this case, the performance of g.DrawImage(...) drawing onto a
Pixmap is terrible (~ 1 second).
Basically, I just need a way to copy a System.Drawing.Bitmap to a
Gtk.DrawingArea in a constant and reasonably quick amount of time. I'm not
sure what I'm doing wrong, but any ideas would be greatly appreciated.

[Mono-dev] Strange .ctor() behaviour
Hi,
Using Mono.Cecil, I inserted custom attributes into an
assembly. Some of the classes in it are Clock, DisplayTime,
Observer,. The attribute is a string of type MyAttribute. Now
after inserting a value and disassembling the assembly, instead of a
statement like the following:
.custom instance void MyNameSpace.MyAttribute::.ctor() = {01 00
} // Its value
It gives
.custom instance void AnotherNameSpace.Clock::.ctor() = {01 00
} // value
While inserting, I gave the correct type of the MyAttribute. The
value I gave is correctly displayed. Its values is correct. Only the
constructor part is the one not intended. There isn't any constructor
even, that matches the above one.
One more thing, if we use ILdasm to disassemble an assembly, is
there any significance to the order in which it displays the types in
the assembly. Got a doubt because Clock was displayed first and I
didn't write it in the source code first.
Thank you.

Re: [Mono-dev] Unloading an Assembly
Hi, The issue is resolved. The mistake I have been doing was, though I loaded the assembly into another AppDomain, I was referencing(using Reflection) it in the CurrentDomain. Also I used MarshalByRefObject in a wrong manner. I thought it should be used by the Assembly Iam loading. It should be used i.e. the class which loads the assembly should derive from MarshalByRefObject. It is necessary for inter domain communication.

[Mono-dev] Documentation or pointers for profiling mono/mini?
Hi, I'm working on a project which involves profiling mono and generating information about the code being run. For example, I'm trying to see how deep the call stack is, or inserting code to the method bodies, to generate stats about the code runs. This is to be done for the jit alone. I've looked through[1], [2], both myself, and through Google's eyes, but haven't found much useful information about the layout of the code. I have the source code, and am looking through mono/mini/mini.c and other files, trying to understand the code. 1. http://lists.ximian.com/pipermail/mono-devel-list/ 2. http://www.go-mono.com/docs/ Any pointers or help would be appreciated.

Thanks for the debug output. It may be easier to install all of Gnome. But, if you're taking the minimalistic approach, try installing the libpanel applet package. Repeat this same process of running monodevelop with the debug logs turned on and install additional packages until you don't get any exceptions with libgnomesharpglue.
